In this paper the principal inscription techniques and the physical properties of femtosecond (fs) pulse written in‐fiber gratings are reviewed. The role of focusing and order walk‐off on the inscribed structures is emphasized.

The femtosecond pulse compressor should be placed in the beam path between the laser and the microscope. Two beam heights are supported: 4.75" (120.7 mm), for Thorlabs' Tiberius laser and Coherent's Chameleon™ lasers, and 4.25" (108.0 mm), for other common commercial lasers. The beam height is set by a base plate that is included with the unit.

In the terminology of electronic instrumentation, femtosecond lasers constitute the world’s best pulse generators, while pulse shaping is the short pulse optical analog to electronic function generators, which widely provide electronic square waves, triangle Femtosecond semiconductor lasers are ideal devices to provide the ultrashort pulses for industrial and biomedical use because of their robustness, stability, compactness and potential low cost. In Femtosecond (fs) laser pulsed excitation of plasmonic nanoparticle (NP)–biomolecule conjugates is a promising method to locally heat biological materials. In this paper the principal inscription techniques and the physical properties of femtosecond (fs) pulse written in‐fiber gratings are reviewed. The role of focusing and order walk‐off on the inscribed structures is emphasized. T1 - Femtosecond laser pulse propagation through aerosol clouds. AU - Alexander, Dennis R. AU - Rohlfs, Mark L.
